The Roman Catholic cathedral of St. Joseph is one of the most important historical buildings in Stone Town, Zanzibar, as well as one of its main visitor attractions.

The church is regularly used by the local Catholic community, with several masses being held each Sunday and occasionally on weekdays.

[1] While its twin spires are easily seen from a distance and from elevated places in Stone Town (i.e., the House of Wonders balconies), the church itself can prove hard to find in the maze of narrow streets of Baghani.

Its main architectural feature is twin spires (like those of Marseille's church) that are one of the easiest elements of Stone Town's skyline to spot from elevated places as well as from the ocean.

[3] The interior is painted with scenes from the Old Testament, all of which have been destroyed due to the poorly done restoration in 2014.
